Specification of Letters Patent.

Application filed October 30, 1917. Serial No. 199,263.

T all wkom z't may concern:

Be it known thatI, EUGENE C. BRULL, a

citizen of the United States, and a resident of the village of Oak Park,in the county of of this invention to improve and refine the machine andto provide a better machine.

A ser1ous ob ection 1n,mach1nes as heretofore constructed is that thefilings get into or spoilingthe bearings.

the bearings, wearing,the same away quickly It is an object of thisinvention to provide means Which pre vents the filings or file dust fromgetting into the bearings, thereby preventing the destruction of thebearings from this cause.

It is further' an 010 oct of this invention to provide a novel 'changingthe throw of the file.

It is finally an object of this invention to provide a filing machinewhich is iinproved in every mechanism and adjustment, permitting quickand acourate adjustment and pro- 7 viding amachine which Will givemaximum service With minimum wear and operating expense.

The invention (in a preferred form) is illustrated,in the drawings andhereinafter more. fully,described.

. On the drawings:

F ig. 4; is an enlarged sectional detail of the mechanism for adjustingthe eccentric drive stud.

Fig. 5 is an enlarged sectional detail taken at right anglewith Fig. 4but loi1gitudinally or" the adjusting mechanism.

F ig. 6 is a fragmentary section taken through the lOwer hood along thefile shaft.

As shown insaid drawings:

l, indicates a suitable base provided with a stand 2,of suitable shap6Which. atthe top is provided with an extension 3-, recessed on one side,the upper face of said extension being formed semi-circular, and thebottom of said recess being similarly formed but revefsed, said twosemi-circular portions being struck from a common center and With thesame length radius.

The work table or hench 4, may be of any desired shape but as shown isroundand is provided with a clownwardly directed circular head 5, Whichis complemental with the curvature of the recessed extension 3 and fitson the same. A scale 6, is provided on the head 5, by means of which theangle of filing may be veryaccurately cletermined.

For the purpose of adjusting said work bench 4, a shaft 7 is journaledinlthe stand 2,at the base of the extension 3, and is held fromlongitudinal movement by a key8, en gaged in a gioove in the shaft. Amilled head 9, isproVided on the outer end ofthe shaft and a worm 10, onthe inner end of the shaft which meshes with a Worm: gear seg ment 11,rigidly secured to the head 5, which is provided with a recess for thispurpose.

For the purpose of clampingthe table in any adjustment complementalapertureS are provided in the extension 3 and head 5, in which isinserted a sleeve provided with an intern'ally threzided axial passage,the threads in opposite ends of the sleeve being reversed. A key Or pin13, is inserted in registering grooves' in the sleeve and eXtensionWhich holds the sleeve from rotation.

Threaded into the innerend of the sleeve Patented NOV. 25, 1919.

is a bolt 14, having a head 15, thereon which fits in a recess in theextension 3 provided for this purpose. A clamp screw 16, is threadedinto the outer end of the'sleeve and 'is provided with a sh0ulderedhandle 17, which bears against th clamping collar 18,

.on the screw shaft Which in turn'fits into a 7 7 sn1table recessm thec1rcular head 5.

7 Journaled in snitable sleeve bearm s 1920 scured in the base 1, andstand 2, is a file holder or shaft2l, provided with 21 socket in itsupper end in which is engaged the shank 22, cf afile 23, which operatesthrongh a suitable aperture in the work bench.

Rigidly secured to the shaft, or file holder 21, is a hood 24, which isprovided with a -dowmvardly extending sleeve 25, fitting over V thebearing sleeve 20, andwhich exclndes all filings from said-bearing.

A ho0d member 26, isrigi dly se cured to the stand 2, by means of screws27. Said hood member;26, fiares outwardly beyond .the lower bearing 19and Working parts,

defiectin *all dust and oil drippings from the bearmgs to,drop upon thefioor.

Oil holes 28, are provided in the bearing* sleeveS which are closed byscrews .129, by

means of Which oil may be inserted in the sleeves to lubricate the sha1t21 A drive shaft 30, is journaled in a bearing sleeve 31, in a hub, 32,integral With the stand 2,and an oil hole 33., and closure screw v '34,is provided therefor. As shown, a mo- 1-. tor 35, is directly. connectedto the drive shaft 30, but Ofconrse a belt pulley or other drive meansmay be secured to said shaft.

' gIntegral with. or. rigidly secured to the inner end of the; driveshaf't 30, is a circular head 36, provided W1 th a doVe tailed groove inwhich fits a cross head 37, having thread- 7 ed engagement with anadjusting screw shaft '38, which ,screw shaft is-held front:longitddinal movement by a spring pressed pin 39, engagmg'1n a groove1nthe shaft 38. alw1th said cross head member 18 a:

' The operationis as follows:

The Work table 4, may be ad usted to any angle desired to file any bevelor other-.

' The desired position is readily ascertained by the gage 6, and afterthe desired ad- 'justment has been effectedthe table;is rigidl clampedin that position by the clamp o ing serew and collar 16 and '18,respectively.

Anfy desired Strokef and speed of the file may be obtained by adjustingscrew 38,

drawings it is seen that 1 have produced a filing machine in which thevarious djustments may be'readily and quickly made and in which theparts'are strong and Will wear fora long time. 7 A

The machine as a whole is greatly refined and Will give long service atminimum expense.

Details of construction may be, varied and numerous changes may beinade. with out departing from the scope of the ap pended claims.and Itherefdre do not desire to limit my application for patent otherwisethan necessitated by the prior art.
